Using Ruby's ElasticSearch gem that uses Kaminari for pagination and the Ruby GraphQL gem, this is a custom connection to bypass additional pagination. This assumes that you've already queried the correct paginated records from ElasticSearch and you're returning an `Elasticsearch::Model::Response` object.
class ElasticSearchConnection < GraphQL::Relay::BaseConnection
def has_next_page
!nodes.last_page?
end
def has_previous_page
!nodes.first_page?

how to access subdomains locally with Rails 5

Subdomaining Localhost with Rails 5

I've been following this blog post on how to set up an api-only Rails 5 application. One of the sections talks about creating a subdomain for your api

Rails.application.routes.draw do
  constraints subdomain: "api" do
    scope module: "api" do

Event-stream based GraphQL subscriptions for real-time updates

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

  • query
  • mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.
